## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ipstack-self-ip-lookup-27f39cc3
```

Example prompt: What IP address and location does IPstack see for me right now — country, city, and timezone?

## When to prefer this

Use this endpoint when an agent needs to quickly determine its own public-facing IP address and approximate geographic location without supplying an IP parameter — ideal for self-location checks, debugging outbound traffic, or coarse geofencing logic where the agent's own IP is the subject of inquiry.

## Known failure modes

- Invalid or missing API credentials returns 401 Unauthorized
- Payment not processed or x402 payment failure returns 402 Payment Required
- IPstack service unavailable returns 503
- Caller IP is private/internal and cannot be geolocated — returns empty or null location fields
- Rate limit exceeded returns 429

## How this service works

Lookup the requester IP as seen by IPstack. Useful for quick agent self-location checks, request debugging and coarse geofencing.

## Output

Returns the caller's detected IP address along with IPstack geolocation data including country, region, city, latitude/longitude, timezone, and ISP information.
